Handheld Infrared Acoustic Imaging Detector for PD and Gas Leak Detection

Product Overview

The Infrared Acoustic Imaging Detector is equipped with a high-sensitivity digital microphone array and is primarily used to detect partial discharges in electrical insulation equipment and pressurized gas leaks. It also supports optional functions such as infrared thermal imaging, internal leakage detection, and other diagnostic capabilities.

Designed with an auxiliary light source for low-light environments, the device supports external sensor integration. The housing is made of aluminum alloy to enhance durability, and both the structural and circuit designs consider explosion-proof requirements. Certain models are suitable for use in hazardous environments (please ensure that the specific model purchased is explosion-proof certified).

 

Key Features

1.High Efficiency

The microphone array utilizes spatial scanning and acoustic localization to quickly determine the presence of faults within seconds.

2.Qualitative and Quantitative Analysis

For partial discharge detection, the device can identify the type of discharge. When used for leak detection, it can provide real-time estimates of leakage rates.

3.Easy to Operate

Ready to use at power-on. The interface is similar to that of a smartphone, allowing intuitive use without the need for training.

4.Powerful Functionality

Capable of detecting all types of pressurized gas leaks, as well as identifying partial discharges and thermal hotspots in electrical equipment.

5.Long-Range, Non-Contact Detection

Able to detect leaks from several meters to over a hundred meters away, ensuring operator safety and reducing the risk of missed detections.

6.Digital Recording

When a fault is identified, the device allows for easy and intuitive documentation of the fault location and details via photos and videos.

Frequently Asked Questions about handheld infrared acoustic imaging detector

What is the handheld infrared acoustic imaging detector used for?

The handheld infrared acoustic imaging detector is designed for visual detection of partial discharge and gas leaks by acoustic imaging. It is deployed in substations, overhead lines and industrial electrical rooms, where it gives maintenance teams continuous or periodic visibility of insulation condition so that defects can be identified before they develop into unplanned outages.

What advantage does imaging give over a single-point reading?

This product overlays the acoustic source onto a visual image, so the operator sees where the discharge or the leak physically is instead of only receiving a number. This shortens the time needed to locate a defect, and produces a photograph that can be attached directly to the inspection report as evidence.

Is installation possible without an outage?

In most cases yes. Because the handheld infrared acoustic imaging detector is installed on the equipment while it remains energised, the work is normally carried out as a live-line operation by qualified personnel following the site safety rules. Where a sensor must be coupled to an earthed screen, bonded connection or gas compartment, a short outage may be required — this is confirmed during the site survey.

Does HUWOR support OEM/ODM and what is the delivery lead time?

Yes. Zhuhai Huawang Technology Co., Ltd. supplies the handheld infrared acoustic imaging detector under its own brand and also supports OEM/ODM supply, including private labelling, custom firmware functions and integration with the customer’s monitoring platform. Standard units are typically quoted with a lead time confirmed at order stage depending on quantity and configuration; sample and pilot orders are supported.

Applications

The handheld infrared acoustic imaging detector is used for visual detection of partial discharge and gas leaks by acoustic imaging. Typical installation sites include substations, overhead lines and industrial electrical rooms. It is applied both on new assets, where the monitoring function is built into the asset from the start, and on existing assets where it is retrofitted to extend the information available to the maintenance team.

How it works

The instrument converts the physical quantity of interest into an electrical signal, conditions and digitises that signal in the field unit, and passes the result to the monitoring platform or to the operator. Condition assessment relies on the trend rather than on a single reading: the value recorded today is compared with the commissioning value and with the historical series for the same measurement point, and it is the direction and rate of change that indicate whether the asset is degrading.

Installation and commissioning

Installation follows three steps: a site survey to confirm the mounting position, the communication path and the power arrangement; mechanical fitting of the sensor or the use of the instrument on the test point; and finally commissioning, where the readings are verified against a reference and the alarm thresholds are set.

Standards and documentation

Type test reports, calibration certificates and installation documentation are provided with the supply. Where a project requires the equipment to be verified against a specific national or utility standard, the applicable clauses should be stated in the enquiry so that the test scope can be confirmed at quotation stage.
